TV royalty Ant and Dec are joining up with the real thing for a new documentary about the work of the Prince's Trust.

The Geordie duo, who host some of the biggest shows on TV, will spend time with the Prince of Wales as the trust gears up to its 40th anniversary in 2016.

The result will be a 90-minute ITV special shown next year.

Ant and Dec, who already work as ambassadors for the trust, said: "We are hugely excited to be working with HRH The Prince of Wales on our first project of this kind.

"We've worked with The Prince's Trust for years and know what an incredible job they do of supporting young people right across the UK.

"This is a unique opportunity for us to get under the skin of a great organisation and its founder, to pose the questions we've always wanted to ask and to see the achievements of the young people celebrated."

The trust, launched by Charles in 1976, works with people aged 13 to 30 struggling with school or unemployment.

ITV's factual commission editor Andrew O'Connell said: "We are delighted to be following The Prince's Trust over a year to celebrate this landmark occasion.

"This special programme will see Ant and Dec spending time throughout the year with the Prince and seeing at close hand the work he does within the trust aimed at enhancing young people's lives up and down the country.

"This promises to be a major event in the schedule and a real treat for our viewers."
